Crocus sativus Stigma Identity & Plant Part
The botanical entity is Crocus sativus L., a sterile triploid crocus that flowers in autumn and cannot set seed, so growers propagate it by splitting corms. The part used is the stigma, the red, thread-like tip of the style. Each flower carries only three, and they are picked by hand and dried. Petals, stamens, the style below the stigma and the corm are not included in this saffron extract.
Saffron is frequently adulterated.
The stigma contains crocins, water-soluble carotenoid esters that give the orange-red color; picrocrocin, which gives the bitter taste; and safranal, the main aroma compound, which forms from picrocrocin during drying.
